I'm attempting my first sweater project and got to a part in the pattern that I just don't understand and every how-to video is confusing me. I'm working on the back piece and the pattern says: BO 3 sts at beg of next 4 rows, then 5 sts at beg of next two rows. BO rem 17 stitches loosely. Does this mean that I bind off 3 sts at the beginning of one row, knit the rest in that row, then bind of 5 stitches for the beginning of the next two rows? The videos I keep watching show the knitter wrapping, then turning the work around. The pattern doesn't mention that. Any help???

Does this mean that I bind off 3 sts at the beginning of one row, knit the rest in that row, then bind of 5 stitches for the beginning of the next two rows?

No, that's not what you do, and you don't do it like the videos, that's for another technique.

BO 3 sts, knit the rest of the row, turn and BO 3 sts at the beg of the next row and do the rest of the sts. Do that again - BO 3, knit the row, BO 3, work the row. Then BO 5 sts, finish the row, turn and BO 5 sts and finish. Then turn and BO all the rest of the sts and you're done.
